i understand that the readability is 0.5 lbs,.however, .does anyone know the accuracy?

Readability is to .1. My car tells me each tire's pressure to the lb. they appear to be in sync. I LOVE the guage and gave out over a dozen as Chistmas presents.

The manufacturer calls the "Accuracy" as the "Acceptable Tolerance" and it is "+/- 0.02 g." Exactly the same calibration standard weight doesn't always read the same number (measurement repeatability). But my 100-gram calibration weight has always read within this "+/- 0.02 g" accuracy. I've found that the "sensitivity", or the "minimum measurable weight", is about 0.03 gram. There is some hysteresis effect to it. That is, after you measured 0.05 gram, then you can reduce the weight to the minimum 0.03 gram. You can't directly measure the 0.03 gram weight without adding some additional weight first, then take away the additional weight. The "reading resolution", or the "Readability" as called by the manufacturer, is, of course, "0.01g." The manufacturer calls the "Accuracy" as the "Acceptable Tolerance" and it is "+/- 0.02 g."

lol.. I have the same question. I think, they meant 0.21 lbs. 21 lbs is a typo.

It only reads up to 440 pounds if I remember correctly. Anything over that would get an error response. Hopefully, this helps.

It reads in pounds or kgs and is very accurate. Weighed a 25 lb dumbbell to test it and it was right on the nose

The specs on their website says the readings displayed will be in .05 degree increments but the accuracy is +- .2 degrees. So if you need more than a .2 degree accuracy, this isn't accurate enough for you.

I have found it very accurate. I use it to weigh all my gear for backpacking and for that it's down to the ounce. I have tested others but this one is the one I'd recommend.

I am not sure what you mean about the thickness of the pages together. The pages are not flimsy. The size is 5.5 x 8.5.As far as the weight goes you are receiving the entire year so I would say it would be the 1.1 pounds.

Seems to be consistent. As far as accuracy goes I can't say. Certain scales weigh me heavier, others lighter.

Dino: I just weighed the UL20a on my digital scale. It came out as 3.4 pounds. Given that there is a possibility that the scale is not 100 percent precise, I'd say the manufacturer's quoted weight listing (3.3 pounds) is accurate. Diplomacy and collegiality among Amazon customers dictates that I not comment on your age or physical capabilities.:-)Mitch

Yes. If you push the on/off button while weighing, it will "hold" the reading. Hope that helps.

I routinely measure 0.04 grams, works for me but I have no way to compare. The calibration seems right on.

It wouldn't be 100% accurate, but close. My guess is the reading would be about 25-50% low.

Yes you just need to set it to grams or oz. I think it went up to ten pounds but I really can't remember as I thru it out many months ago. It was a piece of junk. BTW there's no back light so you'll need to have light to read it.

I have no other device to compare it with so I have no idea of it's accuracy. We use it for comparitive purposes so for that it's useful. The "manual" is very tiny page, with a tiny chart for weighting and frankly I've misplaced it. Other than that, there is little info. However it does seem very well made. I has the feel of a Fluke multimeter.

It does not require calibration, but it sometimes under-weighs by .1 ounce. I bought a set of 1 oz and 2 oz weights and test it occasionally, especially when I get a reading that is exactly 1, 2, or 3 ounces.

Yes. It's accurate to 0.05 ounces (about 1.5 grams) so really small amounts. I have used it for mail also!
